Christoph Becher

Christoph Becher is a Professor in the Department of Physics at the University of Saarland, Faculty of Natural Sciences and Technology. He leads the Research Group for Quantum Optics, focusing on experimental quantum technologies. He is actively involved in major national and interdisciplinary research centers including the Collaborative Research Center TRR 306 QuCoLiMa and the newly established Center for Quantum Technologies (QuTe) funded by the Transformationsfonds.

His research lies at the intersection of quantum optics, solid-state physics, and quantum information science. Key areas include quantum photonics with diamond color centers (especially SiV centers), nanophotonic integration, quantum frequency conversion, and quantum communication using quantum repeaters. His group employs advanced laser spectroscopy and nanofabrication techniques to manipulate single quantum emitters and develop building blocks for quantum networks.

The recent publications reflect a strong trend in quantum technologies, particularly in coupling quantum emitters to nanophotonic structures, quantum networking over fiber, and nonlinear quantum optics with single photons. His work frequently appears in high-impact journals such as Nature Communications, Physical Review Letters, and Nature Nanotechnology.

Scientific Awards:

• Member of acatech (German Academy of Science and Engineering), elected 2020

Advising and Grants: Prof. Becher supervises a dynamic team of PhD students and postdoctoral researchers. He leads and participates in major funded projects including the BMBF-funded Quantenrepeater.Net (QR.N) (20 million Euro, 42 partners), the DFG-funded Collaborative Research Center QuCoLiMa, and the state-funded Center for Quantum Technologies (QuTe) at Saarland University.

Labs and Teams: He heads the Quantum Optics research group at Campus E2 6, Saarbrücken, housing experimental setups for low-temperature spectroscopy, quantum frequency conversion, and quantum networking. His team includes doctoral researchers, postdocs, technical staff, and student assistants, working collaboratively on advancing quantum technologies.
